(1 東南大學土木工程學院 南京 210096; 2 東大特種基礎工程公司 南京 210096)[提要] 介紹了江南大酒店整體平移后采用摩擦滑移基礎隔震的設計。隔震支座為聚四氟乙烯滑移支座。工程設計有效地把結構的整體平移與隔震結合在一起。計算分析表明,采用基礎隔震后,大大提高了結構在罕遇水平地震作用下的可靠度,具有較大的經(jīng)濟效益。
[關鍵詞] 基礎隔震 滑移支座 聚四氟乙烯滑移支座The sliding base isolation design of Jiangnan Hotel which has been moved is introduced. The slip interface is made of Teflon. The movement of the whole building and the sliding base isolation are effectively combined in this engineering. The calculating results show the reliability of the structure is improved apparently under the horizontal action of severe earthquake intensity.
